The air duct production line will produce a lot of material loss during the large-scale processing of air ducts. If it is not handled properly, the loss will be too large, which will cause a lot of waste of resources. Here is how to reduce the material loss of the air duct production line when processing air ducts. .
1. The edge material produced during the cutting process of the board should be applied to the top of the air duct as much as possible. Because the upper layer is concealed, it can be used as long as it does not affect the air duct itself.
2. Special-shaped air ducts are processed in a centralized and unified manner, and the special-shaped pipes are processed as far as possible, so that all the large-size plates remaining in the processing of the special-shaped pipes can be applied to the subsequent straight pipes.
3. Reduce unnecessary and complicated layout in the air duct design, which can reduce the overall material waste.
4. Before processing the air duct, carefully understand the duct structure and specifications on the drawing, so as to cause unnecessary waste when cutting the plate, which is also a key step to reduce the loss.
5. The distance between the air pipes should be as large as possible when connecting, especially the small branch pipes can be processed according to the length of the plate, which can save the waste of air pipe accessories and speed up the efficiency of air pipe processing.
If the customer wants to make the service life of the air duct production line longer, it must be cleaned, maintained and maintained regularly. Let me introduce to you what are the cleaning methods.
1. Manual cleaning method: use a brush to directly process and clean the inner wall of the duct of the air duct production line. The advantage of this method is that it is convenient and easy to clean. But the disadvantage is that the cleaning will not be clean and easy to leave dirt.
2. Gas flushing method: The principle of this method is to transport compressed air through a hose connected to the air pipe, and then discharge the dirt through the compressed air. The discharged dirt will be transported by the air pipe into the vacuum container.
3. Power flushing method: It mainly uses pneumatic or electric brush to remove dirt and then use vacuum collector to absorb.
The duct production line can be defined as the whole process of duct forming is completed by a machine independently. According to the processing technology of the wind pipe, the popular point is that the whole process from the blanking of the coil to the forming of the wind pipe is completed by machine processing equipment without interruption and independently. So how does the duct production line make ducts? Let's take everyone to take a look.
1. Coil material selection and blanking function: 2-6 kinds of coil materials of different thickness or material can be selected.
2. Compression and leveling function: This function is the adjustment process before the coil processing to prevent the generation of waste.
3. Punching, chamfering and grooving functions: This function can complete the production of duct installation holes, avoiding the inconvenience caused by later drilling.
4. Cut-off function: This function separates the sheet from the coil for the next step of processing.
5. Transmission function: It is convenient for the coil to automatically process the next process.
6. Bite: This function realizes the pressing operation of the sheet material and makes the joint angle.
7. Co-plate flange forming: This function is a key step in the production of double-sided co-plate flanges.
8. Bending and forming: This process is completed, and the rectangular duct with plate flange has been formed.
Duct production line manufacturers often need a combination of pipeline equipment production in the daily production process to complete the actual production of the duct. Then in the daily production process, which combination of duct production equipment do we need?
1. Feeding rack: electric feeding rack-table (2 trays)
2. Leveling and beading machine: a set of beading and leveling devices
3. Point punching and square punching machines: four sets of hydraulic angle shearing machines (including molds)
4. Hydraulic shearing machine: one hydraulic shearing machine
The production line can realize the product from coil unwinding, leveling and crimping, shear angle (including CS plug-in flange, TDF self-contained flange and TDC plug-in flange) and cut to length, which significantly improves the air duct Production accuracy and stability. Its working speed is 16m/min, the length error is +0.5mm/m, and the diagonal error is +0.8mm/m. The working capacity of the loading rack can be customized according to customer needs.
Then, we also need to use a multi-function biting machine: suitable for the production of air ducts for ventilation, air conditioning, purification and other devices. According to requirements, it can be made into various square and rectangular thin plate air ducts. Indispensable mechanized equipment such as air duct production.
Next, a common plate flange forming machine is needed: the common plate flange machine is a special equipment for flange forming on the plate connection port of the air duct itself, especially suitable for the production of air ducts with a small cross-sectional area.
Next, it is necessary to support the folding machine for the common plate flange: widely used for the bending of steel plates with a length of 2.5 meters and a plate thickness of 2.5 mm or less, non-ferrous metal plates, and stainless steel plates. The flanging work is for household appliances, stainless steel kitchenware, lighting, and hardware. Forming and processing equipment for cabinets and pipes such as furniture, heating, cooling, and air-conditioning equipment.
Then there is the combination of multi-function corner code and check code punch, so that the equipment combination required in duct production is almost the same.
Ventilation ducts are an important part of the ventilation and air conditioning system, and most of them are made of air duct production lines. However, due to various reasons, problems may occur in the ducts processed by the duct production line.
1. The processing material is not up to standard
(1) Performance: The surface of the plate is uneven, the thickness is uneven, there are obvious indentations, cracks, blisters, scars and rust, etc.; the plane of the air duct sinks, the sides bulge outward, and there is obvious deformation.
(2) Impact: The air duct leaks during operation, and the air conditioning load increases, while the wind life and performance are affected.
(3) Reason: The material is unqualified and cannot meet the demand for making air ducts.
(4) Measures: Before using the duct processing equipment to make ducts, first check the material delivery certificate, material quality certificate, and appearance thickness to ensure that the material is available.
2. The angle of the wind pipe and the angle of the elbow are not accurate
(1) Performance: The two opposite planes and two ends of the rectangular duct are not parallel; the corners are not straight; the diagonals are not equal; the bite is not strict.
(2) Impact: The air pipe connection will be unevenly stressed, the air pipe after installation is not straight, the flange gasket is not tight, the system leaks, causing the air conditioning load loss and shortening the service life.
(3) Reason: The blanking of the board is not accurate; the air pipes are parallel to each other, and the length and width of the board on the opposite side are not equal.
(4) Measures: When unfolding the blanking, the blanks should be squared strictly, and the length, width and inspection diagonal of each blank should be controlled within the allowable range; the blanks after blanking should be controlled Superimpose the two sheets on the opposite side of the air duct to check the dimensional accuracy.
The air duct production line can greatly increase the production speed of the air duct and also improve the quality of the air duct production. There are many kinds of products on the market. How do we judge the quality of the air duct production line?
1. Understand the operation of the quality system of the production enterprise of the full duct production line. The full duct production line is expensive and usually costs hundreds of thousands of dollars. Therefore, before we purchase, we will send a dedicated person to inspect and make a decision. A large-scale, well-equipped, and safe and standard manufacturer is our first choice.
2. Understand whether the full-duct production line consumer enterprise can pass ISO9001 and other relevant standard certifications. Only products that have passed ISO certification can have their quality guaranteed and pass the requirements of engineering projects.
3. Investigate the technical equipment level of the full duct production line manufacturers. Only advanced equipment and technology can produce high-precision and high-quality ducts, so manufacturers with rich manufacturing experience and strong R&D skills are preferred.
4. Understand the product sales of the full duct production line manufacturers. A good product will naturally have a good reputation, and more and more people will buy it. This is an indisputable fact in all walks of life.
